' specification.

My invention relates to improvements in corn-planters; and the objects injview, together with the novel featuresthereof, will hereinafter appear, and be particularly pointedl out in the claims.

In the drawings, Figure 1 is a perspective of a corn-planter embodying my invention. Fig. 2 is a transverse section thereof in rear of the hoppers. rear of the axle. Fig. 4 is a detail in elevation of the trip-disk. Fig. 5 is a detail of the seed-disk, hopper, and pawls.

Like numerals of reference indicate like parts in all the figures-of the drawings.

1 designates the opposite side bars, and 2 -and 3 the front and rear transverse connecting-bars, composing the rearfrarne of the machine. The side bars 1 are provided upon their under sides with bearings 4, and in the same is journaled the transverse axle 5, provided at its ends with ground-wheels 6.

Upon the center of the axle a bearingsleeve 7 is loosely mounted, and from the same there rises a rearwardly-curved seatstandard 8, the end of which is above the rear cross-bar 3 of the framework and is supported by inclined braces 9. A transversely-perforated lug 10 is also formed upon the sleeve 7 and receives alongitudinally-reciprocal pin or bolt 11, having a notch 12 formed in its side near one end. Abracket 13, of substantially U shape, is formed upon the sleeve 7 and is provided with opposite bearings to receive a transverse pin 14. Upon this bearing-pin there is pivoted, a lever 15, provided with a spiral Iiange 16, which engages the recess or notch 12, formed in the pin or bolt. By reason of the spiral formation or disposition given the iiange of the lever vibrations of the latter will cause a reciprocation of the pin or bolt l1 in the bearinglugs 10, as will be obvious. One end of the bearing bolt or pin 11 is connected with a clutcl1-sleeve 17, and the same is designed to be thrown into and out of engagement with teeth 18, formed on the face Fig. 3 is a similar view inl SPECIFICATION forming part of Letters Patent No. 485,560, dated November 1, 1892.

of disk 19, the latter also being provided at diam'etrically-opposite points with triplugs 20. The disk is loose upon the shaft and' 55 is supported in position by a collar or flange 21, formed upon the shaft. By reciprocating the pin or bolt in the manner before described-that is, through the medium of the lever 15-the clutch-sleeve 17 may be thrown 6o into engagement with the teeth of the disk, so that motion will be communicated from the shaft through the clutch-sleeve and to the disk, the latter becoming thus locked upon the shaft and partaking .of its rotation.

The barsl of the rear frame are connected between the cross-bar 2 and the axle with a cross-bar 22, bearings 23 being formed onthe two bars. These bearings laccommodate an oscillating or rocking shaft 24, longitudinally 7o disposed and at its ends extending beyond the bearings. The rear end of the shaft 24 is provided with a head 25, and the same has formed at one side a beveled lug 26, arranged in the path of the lug 2O of the disk 19. The 75 fron-t end of the shaft is likewise provided witha toothed segmental head 27, adapted to rock with the shaft as the latter is operated by the lugs of the disk coming in contact therewith.

l To the front end of the rear framework eyes 29 vare connected, and the same coincide with similar eyes extending from the rear cross-bar 30 of the front or hopper-carrying frame. In this manner the two frames are loosely connected. From the cross-bar 30 depend furrow-openers and seed-tubes 31, and from the same extend forwardly the usual runners 32, connected by a crossbar 33. Hoppers 34 are supported opposite each of 9o the seed-tubes upon the cross-bar 30 and may be provided with rotary seed-disks 35. Yokes 36 have their lower ends pivoted to the bar 30 at the inner side of each of the aforesaid hoppers, and the. upper ends of these yokes are connected by a reciprocating bar 37, the connections being pivoted and made by means of bolts 38a, as shown. The bar 37 is provided at one side of its center with a series of teethv 38, which teeth are directly above roo and engage with the teeth of the segment 27. A coiled spring 39 is connected to the bar at its under side and adjacent toits teeth and also to a lug 40 upon the rear bar 30 of the front frame, so that as the bar 37 is moved in one direction through the'iniinence of the toothed segmental head as oscillated by the shaft 24 the said har, head, and shaft are retracted through the medium of the aforesaid spring 39, and thus after each stroke upon the lug 26 by means of one of the lugs 2O of the disk 19 the said shaft is returned andthe lug 26 again thrown into position to receive a subsequent stroke from the next succeeding lug of the disk.

To each of the seed-tubes there is fulcrumed by a pin 42 a marking-lever 43, each of these levers terminating atits rerrin marking ends and provided at its front end with weights 44, whereby they are in a measure balanced or given the desired weight.

Pivoted, as at 45, to the front sideof the` bar 30 is a lever 46, adapted to oscillate, and l near the ends of the bar 30 pulleycarrying brackets 48 are located, a similar bracket 49 being located between one of theseend `brackv the front ends thereof) and are passed over Flexible cords 50 lead the pulleys 48, one of saidcords being passed Q under the pulley 49 and over the same and l connected to the remaining cord.

From h ere on the-cords lead to and `are connected `with the lower end of the `lever 46, so that, as `will'` Abe obvious, any vibrations of the lever 46 will be communicated to the marking-levers. "Such vibrations are caused by means ot a connecl tion between the bar 37 andlever 46, and the connection inthis instance consists `of a lever l 52, pivoted at one end to the bar 37 and having its remaining or free end loosely engaging the upper end of the bar 46.

The bar 46, 1t w1l l be understood, operates at each recip- `rocation the seed-disk offone ofthe hoppers, i

and `simultaneous With such operation andi the consequent droppin-g of a kernel of corn '1 the markers are operated, and so indicate `the point `at which the kernel is dropped. The

remainder of the operation (that is, `the oper-l,

ation lof the runners and seed-tubes) constitutes no part of my invention, andhence need not be particnlarized. It is onlynecessarytoi employ the marking-levers the irst fou-r or f. tive hills of eachrow,.andafter thishas been;r
